Single user mode

[Vahid Shokouhi]

Hi
Yes, it is possible to gain access via single-user, but single-user 
mode is for root user to configure something as he likes; but if the 
machine is accessible for others, you need to edit "/etc/tty"  to prompt 
for a password in single user mode, although keep in mind anyone with 
physical access to the machine can still retrieve your data through 
various methods.
in /etc/tty note "secure" term which actually has different meaning. It 
means that you consider, for example "console" as a secure mode; so you 
have to change it to "insecure".
After rebooting and entering single user mode, you will be prompted for 
a password to get to the shell prompt.
